Interface Installation The rotary encoder is connected by two or three cables, depending on whether the power supply is integrated into the bus cable or connected separately. If the power supply is integrated into the bus cable one of the cable glands can be fitted with a plug. The cable glands are suitable for cable diameters from 6.5 up to 9 mm. Termination resistors are integrated in the connection cap. These must be switched on if the encoder is connected at the end or the beginning of the bus.

Allowed addresses are between 1 and 99, each can only be used once. The connection cap can easily be opened for installation by removing the two cap screws. The power supply has to be connected once (no matter which clamps). If the terminating resistor is switched on the outgoing bus lines are disconnected. A GSD-file is necessary for installing the encoder. The GSD-file and the detailed user manual can be downloaded from our website (www.posital.com). The connection cap is provided with two LEDs on the backside, which optically represent the device status. This can be very useful for installing and setting-up the encoder.

Interface Programmable Parameters The Profibus-DP interface supports CLASS 1 and CLASS 2 functionality according to the encoder profile*. In addition to these functions the GSD-file supports further features, for example software limit switches. Further more, the following encoder parameters can be programmed directly via the Profibus-DP network without any extra device: Counting Direction Resolution per Revolution Total Resolution Preset Value Velocity Software Limit Switches Function Teach-In (Online Parameterization) This parameter counting direction defines whether the output code increases or decreases when the shaft rotates clockwise. The parameter resolution per revolution is used to program the desired number of steps per revolution. Each value between 1 and the physical resolution per revolution can be programmed. This parameter is used to program the desired number of measuring units over the total measuring range. This value may not exceed the total physical resolution of the absolute rotary encoder. The preset value is the desired position value, which should be reached at a certain physical position of the axis. The position value is set to the desired process value by the parameter preset. The implemented software can additionally deliver the current velocity. This value is transmitted in binary code, 16 Bit, in addition to the process value. It is possible to choose between four different units: steps per 10 ms, per 100 ms, per 1000 ms and revolutions per minute. Two software limit switches can be set. If the position value falls below the lower or exceeds the higher limit switch, a status bit in the process value is set. A special mode is available for commissioning phase of the device. This makes it possible to change parameters while the encoder is in data exchange mode. For continuous operation another mode is available in which the parameters are protected against unintentional changes. * The Profibus-DP profile for encoder can be ordered from Profibus Nutzerorganisation e.v.
